Binding to a custom control property

问题 Hello I have a custom control. This custom control has it's DataContext set to an entity. In my custom control I then bind some TextBlocks to various properties of this entity.

阅读更多关于 How to improve performance of WPF Grid control (.NET 4.0/4.5)?

Problem : Performance is a key

Allow users to resize Expander in WPF

阅读更多关于 Allow users to resize Expander in WPF

问题 I have a lot of C# and WinForms experience but am a newbie to WPF. I have a Window with an Expander which expands downward. Much like the question box I'm currently typing in, I'd like users to be able to dynamically resize the Expander by clicking over a glyph at the bottom (like this question box) and dragging the expander to the desired size. Can anyone provide the XAML (and any additional code) to do this? This is what I have so far: <Expander Header="Live Simulations" Name=

WPF ShaderEffect with PS 3.0 shaders

阅读更多关于 WPF ShaderEffect with PS 3.0 shaders

问题 Where could I find examples of PS 3.0 shaders used as ShaderEffects for WPF 4? I'm looking for tutorials, presentations, any resource on this matter. 回答1: The best information you're going to get is that of the MSDN documentation for the ShaderEffect class in WPF 4.0. Were you looking for anything more specific? 回答2: In fact, there still aren't any resources at all on WPF + PS 3.0 (at least after searching 20 minutes on the web). You'll have to wait or create your own PS 3.0 shaders. 来源：

问题 I wrote a WPF application in C# using VS 2010. The application will run fine in debug mode using Visual Studio, but when I go to run the .EXE from the bin\release folder, nothing happens.

My solution contains 2 projects, both of which use .NET 4.0 framework, and I have .NET 4.0 installed on my PC. I have tried on
